Multi-Tube Vortex Mixer NMVM-100 is a high-capacity vortex mixer designed with brushless DC motor to provide gentle to vigorous mixing of reagents up to 50 test tubes in a single run thereby making the experiment efficient and quick. Vortexing action is created by securing the top of the vessel in place while allowing the bottom to move freely in a defined orbit. It is microprocessor-controlled and a maintenance free motor with quiet operation offers added advantage.
